does anyone sell one?

believe I've had them in the past but Brattons catalog does not list one.

drained the trans oil today and there were a few little filings in the plug......
 
I made my own for engine trans and rear end using 1/4” long 1/4” diameter high strength magnets I bought online. Just drill into drain plugs 3/16” deep 1/4” wide and stick them in they will hold themselves no glue needed very difficult to get out. When I change the oils the plugs are always loaded with “fuzz” that would have been circulating otherwise. I believe them to be very effective at keeping the oil’s free of fillings. Cylinders wear and everyone grinds a gear now and then.
 
If it's a pipe thread McMaster-Carr has them. Don't be alarmed the first time you see how many crumbs are stuck to it.
 
I believe that babbitt is non-magnetic. However, cotter pins fatigue and wind up in the pan. What else is magnetic that would stick to a magnetic drain plug?
 
As pistons go up and down the rings take off microscopic scrapings "the black fuzz" of the cylinder walls, esp prevalent after honing the cylinders.

I think he is asking about the transmission drain plug.

I agree, McMaster-Carr has magnetic plugs. I also use one in my Mitchell O/D and rear end.

Just a point of interest...
I have magnetic plugs in all three locations:
engine, ****** and rear end.
When I pull the plugs to check/drain oil, I always get
some 'dust' on the plugs. Not very much, but a little.
I highly recommend them.
I think I got them at McMaster-Carr.

I've been using a magnet on every drain plug (4 per car including O/D) for years. I just put the magnet on the plug and screw it in. It never moves and It's easy to clean when I pull it off the plug. They cost a matter of cents each.
